I've been doing a lot of reading and searching but still can't find a definite answer...
My understanding is that I need to root the device to flash a custom rom
But from the instructions for noobs, they don't usually specify that I have to root
I assume that rooting is a pre-requisite for everything...but then some roms advertise that they are rooted (for example, LeoFroYo)
So it the rooting process tied to the rom itself and I have to root everytime I flash a new rom (if the rom is not rooted)? Or is it universal like HSPL on WinMo?
Rooting is per rom. What is required to flash a custom rom is having an unlocked bootloader and a custom recovery image. From there you can flash a pre-rooted rom.
The root instructions assume that you're gonna keep using the stock version with root abilities added on top. Whereas if you're using flashing something like CM, that already has root and OS tweaks.

Thanks! So does that mean when I get my phone out of the box, I have to root it once over the stock rom before I can flash any custom rom?
You need to root the phone originally and flash a custom rom. The "pre-rooted" means the rom is rooted. So if you flash that rom then you wont lose root. If you flash an un-rooted rom then you will lose it. So go through the steps and unlock your bootloader then flash a custom recovery image. Then decide which rom you wanted and flash it. All the custom roms are rooted.

That explains it. Thanks for your answer
one more question:
I take it as when bootloader is unlocked, there's no way to lock it again? Not even flashing the stock boot image?
No, once you unlock the bootloader, it stays unlocked.
Just to be clear here you don't _have_ to "root your phone once"
On _most_ phones you need an exploit to be able to get to the bootloader, this exploit is often referred to as rooting. After the exploit you generally have superuser access until you reboot, on some phone this may allow you to get at the bootloader and write anything you want there (E.G. an OS that give you superuser access at boot time)
However the N1 lets you issue the command "fastboot oem unlock" that unlocks the bootloader, from there you can flash a recovery image that will allow you to flash the main OS without having access to Google's release signing keys. Hence you _could_:
1. Bootloader unlock
2. Flash Custom recovery
3. Flash Custom OS
Without ever actually having "root" access, it just happens that most Devs prefer having root access available in both recovery and any custom rom they cook up.
A co-worker recently got a new capitvate from AT&T, and he asked me to root the phone for him. I kept having issues with the phone saying that the phone didn't have the correct signature on the file. I was able to get root on the phone with the superoneclick root but certain programs that needed root would not work properly. So, the work around was to flash using ODIN to a known good unlocked stock ROM. After, flashing to a good stock ROM where the bootloader was not locked I was then able to root and put custom ROM on the phone.
I have an N1 that I unlocked and rooted and was running CM7 RC1 when I decided to try the stock Gingerbread. This switch went perfectly, but now I don't think I want to stay on the stock GB but I can't seem to get ROM Manager to boot into recovery to allow me to flash another ROM. Do I have to do something differently now? BTW, I do not have root on the 'new' GB.
Thanks.
Unless you flashed a pre-rooted version of Gingerbread, you will have lost root and your custom recovery...
If this is the case, you have two options:
1 - Flash a custom recovery through an unlocked bootloader.
2 - passimg back to an older version of Android and root again...

This is your problem. ROM Manager installs a custom recovery, but only when your phone is rooted. You need to re-root GB.
Can I ask them how people flash custom recoveries without having root? I see threads all over the place that say that you don't have to root your phone to run these custom ROM's.

You have to root, but you don't have to unlock your bootloader.
You have to do one of the things:
1) Root.
2) Unlock the bootloader.
Rooting allows you to bypass security mechanisms from within the OS, and flash the custom recovery from there.
Unlocking the bootloader turns off the security mechanisms, and you can flash whatever you want directly from bootloader.
Both achieve the same thing, but in different ways.
Root privileges in OS are lost upon official upgrades.
Unlocked bootloader is never lost.
Unlocked bootloader allows for an easy way to gain root in the first place, regardless of the ROM.
How does an unlocked bootloader allow me to flash whatever ROM I want? ROM Manager won't run without root? Am I missing something? I've read the wiki's and threads about rooting an N1 and they all just seem to stop at unlocking the bootloader, well, my bootloader is unlocked but I can't get it to boot into CWM so that I can select another ROM. Is there another way to do this?
ROM Manager is only one, and not the most successful nor most powerful, way to flash ROMs or recovery. ROM Manager was made for non-understanding people to make the process look and feel easier. The most powerful way is directly from bootloader - which needs to be unlocked to allow it.
If you read all the threads, you'll see that unlocking the bootloader is just a first step - you can look carefully at "installing custom ROM" guide in Wiki. Or, for example, here:
http://forum.xda-developers.com/showthread.php?t=636795
Read the Wiki, look for recovery installation instructions using unlocked bootloader, execute. I suggest Amon_Ra's.
im useing ota 2.3.4 and ive tried everything to root the nexus one universal,z4,gingerbreak i have the bootloader unlocked but it will not root however gingerbreak did install su i thought my G2X was a trip this thing is giveing me more grey hair somew one have a solution
I had this problem and just managed to figure it out today (through the power of google). Superboot, oneclick and gingerbreak all don't work for 2.3.4 as of right now, so you have to use the PASSIMG method to flash an older version and root from there.
I found a good guide, but given that I've been a lurker for the past couple years as opposed to a regular poster, I can't link it. In lieu of a link, I suggest a search query such as "root 2.3.4 nd1razor"
Your bootloader is unlocked. No need for all that crap. Put the su zip on your sd card. Flash custom recovery via fastboot. Boot directly into the new recovery. And flash the su.zip from the recovery. You're rooted. The end.
you just need to flash custom recovery via fast boot or rom manager.then you can flash custom roms (which mostly have root along with tweaks) via recovery

I also unlocked the bootloader!
I put this ROM:
http://forum.xda-developers.com/showthread.php?t=1084726
But I still do not have root permissions ... Why?
You have them, but probably don't know how to use them. How do you check for them?
How did you put the ROM? Did you flash custom recovery?
Yes, i flash recovery-RA-passion-v2.2.1.img
Now my rom is: MIUI-1.9.16
The strange thing is that I managed to install the rom and recovery without having root permissions
Not strange. You don't need root. You have unlocked bootloader......

Thanks, you're very kind!
How do for get root permissions ?
The ROM includes them. When you're inside the ROM, you have root.
You are right !!!!! I just had to change the parameters with superuser
thanks
P.S.: Sorry for my ignorance
Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks
Figured out. Thanks
